In this paper, the change in addressing characteristics of an AC Plasma display panel with Sc-doped MgO protecting layer are investigated with the variation of operation temperature, addressing waiting time, and scan voltage level during address period using ramp addressing pulse. The addressing voltage in the cell which is addressed long time after reset period is higher but showed narrower distribution of addressing discharge event than other cell. This phenomenon is assumed as a result of the increased wall voltage loss and the enhancement of priming effect due to the electron emission from the Sc-doped MgO protecting layer. A modification of driving waveform for scan electrode is suggested to minimize the wall voltage loss and utilize the priming effect due to the electron emission from the protecting layer, and the improvement in addressing characteristics is presented.
